Study sheds light on dengue fever

UK scientists have improved their understanding of dengue fever in research that could aid the development of a vaccine against the tropical illness.

Dengue fever is common in south and south-east Asia, the Pacific, and parts of Africa, Central America, South America and the Caribbean.

It is spread by mosquitoes and causes high fever, joint aching and vomiting, as well as internal bleeding if left untreated.

Scientists at Imperial College London have now identified a set of antibodies that are produced by the human immune system. Although they are supposed to help fight the dengue virus, these antibodies actually appear to help the virus to infect more cells.

The researchers say that the discovery, which is published in Science journal, may help to explain why people who catch dengue fever for a second time tend to experience more severe symptoms.

Lead author Professor Gavin Screaton, head of the department of medicine at Imperial College London, commented: 'Our new research gives us some key information about what is and what is not likely to work when trying to combat the dengue virus.

'We hope that our findings will bring scientists one step closer to creating an effective vaccine.'
